GAOTek Light-weight DC Clamp Meter measures DC leakage and low current with a resolution of up to 0.01 mA and provides high accuracy and performance adopting the latest CT and digital integration technology. It is light weight and easy to carry which can perform multiple additional functions such as on-line monitoring, historical data inquiry, active curve drawing, data storage and printing, zero adjustments and so on. It can be widely used in the field of electricity, communications, meteorology, railroad, oil, construction, scientific & research teaching institutes, industrial and mining establishments, car circuit maintenance.

1. Start-up, Shutdown

Press key to start up, LCD display will be turned on

Press the key again to shut down the meter

After starting up, if the Clamp meter is left idle for 5 minutes, the LCD displays a message that the meter will shut down automatically. After flickering for 30s, it will shut down formally to reduce battery consumption

In case key is pressed when the LCD was flickering, the meter will continue to work for 5 minutes

2. Current Measurement

Dangerous！Please don’t use it to measure current higher than 300 A; otherwise there would be risk of electric shock which causes personal injuries or equipment damages.

Power on

Close tothe measured conductor, press the ZERO key to reset

Press down trigger to open clamp head and clamp to-be-measured conductors. (Pay attention to see that the clamp heads must be totally closed)

Clamp live wire and null line together is to measure leakage current of electrical equipment (Note: 2 lines)

Clamp earth wire is to measure grounding line leakage current of electrical equipment(Note: single line)

Clamp main line is to measure total current of that main line (Note: single line)

Note: In order to ensure the accuracy before every measurement, adjust zero close to the wire and then clamp into the current line to test

Read LCD display data. In case symbol was displayed, it means that current of the measured line is beyond the maximum limit of this meter. In this case, please shift the gear with much higher range limit

In locations where the data is difficult to be read, please use the data holding function. If [DH] symbol is displayed, please discharge data holding state first, and then do the test

Do not test DC current beyond 7A. When the input current is more than 7A, the meter reading may become small, and does not display the over range OL symbol

3. Peak Holding

Pressing key continuously in the course of measurement (More than 3 seconds), the leaker will capture current peak values of lines in this period of time. After releasing the key, it will then return to the measuring state.

4. Hold, Storage and Access Reading

Press key for a short time in the course of measurement (less than 3 seconds), symbol will display. The leaker will hold current measuring data and automatically store in the memory with a unit ID. Press key again to release the hold state and the leaker will continue to measure data. In case stored data reached to 60 groups, press key again and the “” symbol will display, which means storage memory is full; press key to cancel

Press + keys to enter into data access mode and display Unit 1 storage data automatically. Then press key again to turn to the page of stored data. will display when there is no data stored in the memory. Press key to exit data access mode

After entering into data access mode, press key for more than 3 seconds to clean up all stored data. When the leaker displays “” symbol, it means that it has finished clean-up process, and then returns to the measuring state automatically.

How to Change Battery

Warning! It is dangerous to carry out test when the battery cover plate is not on its position.

Please pay attention to the polarity of battery to avoid damaging the leaker

Chang the low battery in time

If you expect not to use the meter for a long time, please get off the battery to storage

“” symbol means the battery is low and need to be replaced

Press key to shut down the leaker. Before opening the battery cover, please confirm the leaker is in off position and then replace

With qualified new battery, special attention shall be paid to the polarity of battery. Cover the battery cover plate
